New build mastic in Brightwalton

New build mastic in Brightwalton, done properly

Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We work on plot handovers, skirting & floors and show homes, and people most often call us about shower seals failing in the first year or two and sealant applied over dusty or wet surfaces.

Around Brightwalton, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What new build mastic looks like in Brightwalton

When it is not the sealant

Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant will not put right:

  • Broken tiles or a split tray
  • Movement caused by a poorly fitted tray or bath
  • Structural cracks in walls or ceilings

If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

Surfaces we seal

  • Skirting & floors
  • Bathrooms & en suites
  • Plot handovers
  • Windows & doors
  • Kitchens
  • Show homes

Aftercare tips

A little care helps the new joints last. Our advice:

  • Look at the sealant regularly in the first couple of years
  • Keep water off fresh sealant until it has cured
  • Use the extractor fan every time you shower
  • Do not seal over failed sealant yourself

Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.

If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Your questions about new build mastic in Brightwalton

What guarantee comes with new build mastic in Brightwalton?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

Is Brightwalton within the area you cover?

Yes. Brightwalton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can I send you my snagging list?

Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we’ll do.

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all.

Can you quote for more than one area?

Yes, we can. More than one area can go on one quote.

Can you do plot mastic on a new development?

Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.

When is the best time to reseal in a new build?

Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.

Should I go to my builder first?

Start with your builder while their snagging or warranty period runs. If that does not work out, we are happy to quote.

Landlords, agents and businesses in Brightwalton

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

We also work for property managers and facilities teams in Brightwalton and across West Berkshire. We can quote a run of properties together, and we are fully insured.

What we do, step by step

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. For a village or hamlet like Brightwalton, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. The old bead comes out in full, with no layer left behind.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. We check every joint and tell you how long each needs to cure.

How to prepare

  • Try not to wet indoor joints just before the visit
  • For business premises, tell us about site rules or sign-in
  • Clear items away from the joints we’re working on

What affects the cost of new build mastic

Call for a quick quote. The main things that affect it are:

  • The type of sealant required
  • The size of the job
  • Mould in or behind the old joints
  • How much old sealant there is and how hard it is to remove

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Helping us quote

Photos by email are helpful but not essential. Try to tell us:

  • Whether it has been sealed before
  • Photos by email, if that’s easy
  • The type of property
  • The problem you’ve noticed

We quote each job on its own. Just call 0345 464 0079 or email us with the details.

What the job involves on each surface

Plot handovers

We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed.

Bathrooms and en suites

New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.

When to call us in Brightwalton

The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.

Most people get in touch after spotting something like this:

  • Shower seals failing in the first year or two
  • Sealant work across a run of new homes
  • Cracked caulk along new skirting
  • Sealant that never bonded to the surface

For jobs in and around Brightwalton, choosing the right material for each joint is as important as a tidy finish.

  • How hidden problems are handled
